SPECIFICATION forming part of Letters Patent No. 615,102, dated November 29, 1898.

Application filed April 12, 1898. Serial No. 677,287. (No model.)

To all whom it may concern:

Be it known that we, GEORGE ALBERT PEN- ROSE and THOMAS FLoRIsroN PENROSE, of Meredith, in the county of 'Woodruff and State of Arkansas, have invented a new and Improved Jack, of which the following is a full, clear, and eXact description.

The object of the invention is to provide a new and improved jack more especially designed for use in railroad trackwork for shifting the rails longitudinally for equalizing the joints, the jack being simple and durable in construction, very effective in operation, and easily applied and moved about from place to place.

The invention consists of novel features and parts and combinations of the same, as will be described hereinafter and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a side elevation of the improvement as applied. Fig. 2 is an enlarged side elevation of part of the same, with part in section. Fig. 3 is a similar View of the same with parts in a different position, and Fig. 4 is an enlarged transverse section of the improvement on the line 4 4' of Fig. 1."

The improved jack is provided with two clamps A and B, preferably made U shape to straddle adjacent rails C 0, keys A B, respectively, being also provided to fasten the said clamps securely in place on the rails. As indicated in Fig. 4, the key A passes through apertures in the lower end of the clamp A and abuts against the under side of the base of the rail, so that when the key is driven into placethe clamp is securely fastened to the rail. The clamp B is fastened in a similar manner to the rail 0 by means of the key 13.

In the upper portion of the clamp A is fitted to slide longitudinally a bar D, pivotally connected at its other end with the clamp B, and on the extreme upper end of the said clamp A is fulcrumed a hand-lever E under the control of the operator. The hand-lever E is pivotally connected by a link F with a grip G, formed with an aperture, through which the bar D extends, the grip G when tilted into an angular position engaging with two edges (the top and bottom edges) of the bar D, as is plainly illustrated in Fig. 2; but when the grip G is in a right-angular position to the bar D, as indicated in Fig. 3, then the grip can slide loosely on the said bar without gripping the same. A foot F on the link F is adapted to engage the grip G to hold the same in a vertical position for shifting the grip on the bar.

The operation is as follows: The clamps A and B are fastened to the rails C 0 near their adjacent ends, as indicated in Fig. 1, the bar D sliding loosely in the clamp A and in the grip G on the bar D. Now when the lever E is in the position shown in Figs. 1 and 2 and a swinging motion is given-t0 said lever in the direction of the arrow a and the link F has pulled the grip G from its normal vertical position into a tilted or angular position then the grip edges grip the bar D, and upon further movement of the lever E in the direction of said arrow at the link F and grip G are caused to pull the bar D from the left to the right, so as to move the rail 0 toward the rail C. When the lever E is swung in the inverse direction of the arrow a, then the link F first pushes the grip G into a rightangular position relatively to the bar D and at the same time moves the foot F in contact with the said grip at the time the latterstands in 'the right-angular position. A further movement of the lever E in the inverse direction of the arrow a causes the grip G to slide loosely on the bar D, so as to finally reach a position to take a new grip on the said bar on the return movement of the lever E in the direction of the arrow Ct. Thus it will be seen that by working the lever E forward or backward, as described, the grip G pulls on the rod D when the lever swings in the direction of the arrow a and slides loosely on the barD when the lever E moves in the inverse 9 direction of the said arrow. Thus the rail 0 is gradually moved with its end up to the end of the other rail 0 to assure a proper joint between the two rails.

Upon removing the keys A and B the entire device can be readily reino'vec'i from the rails and taken to the next adjacent rails for adjusting the same for the purpose mentioned.

The device is very simple and durable in construction, is not liable to get out of order, and can be readily applied and easily manipulated in the manner described.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. A jack, comprising two clamps adapted to be fastened to the adjacent parts to be 0perated in, a bar connected with one of the clamps and slidable on the other, a grip for the said bar, and a lever connected with the grip to draw the latter with the bar in one direction, or to slide the grip loosely on the bar in the opposite direction, substantially as shown and described.

2. A jack, comprising two clamps adapted to be fastened to the adjacent parts to be operated in, a bar connected with one of the clamps and slidable on the other, a grip for the said bar, a lever connected with the grip to draw the latter with the bar in one direction, or to slide the grip loosely on the bar in the opposite direction, and a link between the said lever and the grip and provided with a foot for holding the grip in proper position relatively to the bar to move the grip loosely on the bar, substantially as shown and described.

3. A jack, comprising two clamps each having a key for fastening the clamps to adjacent rails, a bar pivoted on one of the clamps and fitted to slide in the other, a lever fulerumed on the clamp in which the bar slides, a link pivotally connected with the said lever, and a grip engaging the said bar in such a manner that when standing at an angle thereto it grips the bar, and when moving at a right angle the grip slides on the bar, substantially as shown and described.

i. Ajack, comprising two clamps each having a key for fastening the clamps to adjacent rails, a bar pivoted on one of the clamps and fitted to slide in the other, a lever fulcrumed on the clamp in which the bar slides, a link pivotally connected with the said lever, a grip engaging the said bar in such a manner that when standing at an angle thereto it grips the bar, and when moving at a right angle the grip slides on the bar, and a foot on the said link, for holding the grip in a slidable position, as set forth.
